SASH-CORID FAiiTEITER.

Application filed September 1, 1821. Serial No. 497,602.

To all whom it may concern.

Be it known that I, ARTHUR WV. NELSON, a citizen of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Cord Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved sash cord fastener and one object of the invention is to provide a cord fastener which is so constructed that it may serve not only to connect the sash cord with the sash but also serve as means for preventing thewindow from rattling.

Another object of the invention is to so construct this sash cord fastened that the weight of the sash weight will serve to hold a roller in engagement with the window frame so that the sash will be firmly held against rattling but permitted to be easily raised or lowered.

Another object of the invention is to provide a sash cord fastener which is so constructed that a sash cord of the chain type may be easily connected with the fastener and readily disconnected from the same when desired.

This invention is illustrated in the accompanying drawings, wherein: p

Figure 1 is a vertical sectional view through a window structure having the upper and lower sashes provided with the improved cord fasteners. the view being taken along the line 11 of Fig. 2.

Figure 2 is a vertical sectional view taken along the line 22 of Fig. 1.

Figure 3 is a transverse sectional view through a window structure having the cord fasteners connected with the sashes.

Figure 4 is an enlarged view showing the fastener in elevation and applied to a window sash.

Figure 5 is a view in elevation showing the structure of Fig. 4 viewed from the right.

This improved device is to be used in connection with the upper and lower sashes 1 and 2 of a window. These sashes 1 and 2 are slidably mounted in the window frame 3 between the strips or spacing heads 4 and these sashes will be provided with the usual weights 5 carried by flexible carriers shown in the present illustration as chains 6 which pass over pulleys 7. So far the structure'is a conventional window structure.

in order to connect the weight carrying chains 6 with the sashes 1 and 2, each of the sashes will have each side bar cut out to provide a pocket 8 which is positioned at the lower end of a. groove 9 which is cut from the upper end of the sash. A plate 10 is positioned in the pocket 8 and is secured by screws 11. This plate 8 carries a lever 12 which is of the bell-crank type and is pivotally connected with the plate 10 by means of a post 13, the outer end portion of which is enlar ed to retain the lever upon the post. This lever 19. has its horizontal arm terminating in a hook 1 1 for engaging the end of the weight carrying chain 6 and has its vertical arm carrying a stem or axle 15 upon. which is rotatably mounted a roller 16. From an inspection ofFig. 5, it will be readily seen that when the chain 6 is con-, nected with the hook it, the weight of the window weights 5 will cause this lever to be held in a position with the roller engaging one of the heads 4:. The pressure of the rollers against the heads will cause the window sash to be forced in close contact with a second bead and this will prevent the window from rattling. It will thus be seen that the device serves as means for connecting the weight carrying chain with the window sash and also serves as means for preventing the window sash from rattling. It should be noted that the plates are positioned approximately midway the height of the window sash and therefore the pressure of the rollers will be evenly applied and the window sash will be held against rattling in a very efficient manner. By drawing the lower sash forwardly when moving it up-- wardly and by moving-the upper sash rearwardly when drawing it downwardly to an open position, the sashes can be easily moved as this will do away with a portion of the frictional binding between the window sashand frame. When it is desired to remove a window sash from the frame and it is necessary to disconnect the chains 6, it is simply necessary to'unhook the chains from the hooks 14.

I claim:

1. A window structure comprising I a frame, a sash slidably carried by said frame, suspending means for said sash including a flexible carrier, and engaging means carrain ried bV the central portion of said sash and including a pivoted element engaged by the carrier and moved by the action of the suspending means into engagement with the frame to hold the sash against rattling and exclude weather.

2. The structure of claim 1 having said element pivoted intermediate its length and provided with carrier engaging means at one end and a frame engaging element at the other end.

3. The structure of claim 1 having the said element in the form of a bell crank lever pivotally mounted at the junction of its arms having one arm provided with carrier engaging means, and a frame engaging roller carried by its second arm.

4:. A window structure comprising a frame provided with a pair of window stops, a sash slidably mounted between said stops, a weight, a weight carrying chain, and means for connecting the weight chain with the sash, said means including a bell crank lever p votally mounted on said sash and having a horizontal arm connected with the chain and a vertical arm provided with a roller for engaging one oi said stops and moving the sash into engagement with the other of said stops when the lever is moved by the action of said weight.

5. A window structure comprising a frame provided with a pair of window stops, a sash slidably mounted between said stops and intermediate its height having its side edges provided with recesses forming seats having shoulders at their upper and lower ends, weights, weight-carrying chains, and means for connectin the weight carrying chains with said sasli, said means each comprising a plate secured in one of said seats with its ends engaging the shoulders at the upper and lower ends of the seat, a bell crank lever pivotally connected with said plate and having a horizontal arm and a vertical arm, the horizontal arm terminatin in ahook portion engaging said chain, and a roller carried by the vertical arm and engaging one of the stops to move the sash into engagement with the other stop and 101d the sash against rattling when the lever is moved in an operative direction.

6. A sash cord fastenercomprising a plate adapted to be secured to the side edge of a window sash, a bell crank lever pivotally mounted on said plate, one arm of said lever being provided with means for engag ing a sash cord and a roller carried by the other arm of said lever and adapted to engage the side of a window stop when the sash cord fastener is secured to the edge of a sash, and the first mentioned arm of the bell crank lever is connected with the sash cord.

In testimony whereof I have hereunto set my hand.

ARTHUR V. NELSON.
